Spatially differentiated duopolists set higher-than-monopoly prices at some distances. This phenomenon is shown to occur in any finite- dimensional space for a class of reservation prices that covers concavity and convexity in perceived distance from a design. But an upper bound on the...

This paper considers a situation of two sellers of perfectly substitutable items competing in publicly announced reserve prices to induce potential bidders participation at their auction. After learning their own valuations and upon observing the reserve prices, potential bidders make a...

We model a homogeneous product environment where identical e-retailers endogenously engage in both brand advertising (to create loyal customers) and price advertising (to attract 'shoppers'). Our analysis allows for 'cross-channel' effects; indeed, we show that price advertising is a substitute...

The paper analyzes a spatial pattern of goods market integration in Russia. By the spatial pattern is meant a state of each individual region of the country: whether it is integrated, and if not, whether it moves towards integration. Time series of the cost of the basket of 25 basic foods across...

We model a homogeneous product environment where identical e-retailers endogenously engage in both brand advertising (to create loyal customers) and price advertising (to attract 'shoppers'). Our analysis allows for 'cross-channel' effects; indeed, we show that price advertising is a substitute...

We study an equilibrium sequential search model where buyers have potentially downward-sloping demand and with bilateral heterogeneity in buyers' search costs and firms' production costs. We show that downward- sloping demand and heterogeneity in production costs are necessary to ensure price...

In many markets it is possible to find rival sellers charging different prices for the same good. Earlier research has attempted to explain this phenomenon by demonstrating the existence of dispersed price equilibria when consumers must make use of costly search to discover prices. We ask...

Clearinghouse models of online pricing---such as Varian (1980), Rosenthal (1980), Narasimhan (1988), and Baye-Morgan (2001)---view a price comparison site as an 'information clearinghouse' where shoppers and loyals obtain price and product information to make online purchases. These models...
